### What is the diameter of a circle whose area is equal to the what is the area of a circle with diameter 2 5 cm

Find the diameter of the circle whose area is equal to the sum of the areas of two circles having radii 4 c m and 3 c m. View solution There are ________ semicircles in a circle. The diameter of a circle is 2 centimeters. What is the circle what is the area of a circle with diameter 2 5 cm 1 cm We know that, radius is half of the diameter. Radius = (Diameter) / (2) Radius = 2 / 2 Radius = 1 cm Hence Radius is of 1 cm. The circumference of a circle is 5 cm. What is the area of what is the area of a circle with diameter 2 5 cm Area of the circle = 6.25 cm^2. Step-by-step explanation: The circumference of a circle is 5 cm. we need to find the area of the circle. Formula for the circumference of a circle = 2r. r is the radius of the circle. 2r= 5. Divide by on both sides. 2r= 5. divide by 'r' on both sides. r= 5/2. Area of the circle = r^2. r= 5/2
